Olivia von Halle's silk-satin 'Daria' pajamas are inspired by the lounging styles worn by Coco Chanel and her contemporaries in the '20s. Designed to look just as chic at home as it does in your day-to-day wardrobe, this two-piece comprises a short-sleeved shirt and sleek culottes. The white piping adds definition to the fluid fabric.
